• PubMed Abstract: 
  

  The transfer of photosynthetic electrons by the ferredoxin PetF to the [FeFe] hydrogenase HydA1 in the microalga Chlamydomonas reinhardtii is a key step in hydrogen production. Electron delivery requires a specific interaction between PetF and HydA1. However, because of the transient nature of the electron-transfer complex, a crystal structure remains elusive. Therefore, we performed protein-protein docking based on new experimental data from a solution NMR spectroscopy investigation of native and gallium-substituted PetF. This provides valuable information about residues crucial for complex formation and electron transfer. The derived complex model might help to pinpoint residue substitution targets for improved hydrogen production.
